Oh I had a pair of those roller skates with steel wheels! They made a heck of a din! (very satisfying) I once skated into the sweet shop and failed to stop. I crashed into their display cabinet and cracked the glass.
I also remember getting from A to B along the tops of walls, never just on the pavement. And we all had high stilts made of bits of wood.
I used to go horse-riding and we'd get up to all sorts on those ponies. Bareback, hanging on underneath, galloping hell for leather in wild races etc.
Dare I say my favourite pony was called...er...Nigger!! (Oh dear!)
